Creepy Drawing kid did at my work

I work at a restaurant and we put the kids' drawings up on the wall. My coworker just sent me this picture that a child drew tonight and it really freaked me out. He said the child was between 8-12 and just left it on the counter and walked out

I got in trouble in kindergarten because we had to draw happy birthday cards every time it was someone's birthday. For about 12 straight birthdays I drew the words happy birthday and a picture of me shooting the birthday boy or girl in the head. Didn't get caught until number 12 lol. After that I went to putting them all in a tornado. Still don't have the urge to kill anyone lol and I'm 24 now.

the only thing is that it looks like the drawing and handwriting of a 5/6 yo instead of a preteen. also, i don't know about "normal" but the kid could be getting bullied a school or having trouble at home and really feel that way.

My parents used to save drawings that I did. One time I went to look at them, at about age 13. It really creeped me out, there was a pic similar to this, that I had done at age for. It said "I want to kill me". Looking back I see it as a red flag for mental illness. Its important to get treated sooner than later, but unfortunately lots of people just see these drawings as cute or having an active imagination. Unless the kid straight up says its just something they saw in a movie/video game, it could be cause for worry.
